How to Repair a Mopar Wiper Arm
Mopar wiper arms are a lot like other wiper arms in one sense: They don't offer much opportunity to troubleshoot once something goes wrong with them. The arm itself latches into your vehicle's wiper blades and connects to the wiper system's pivot. Essentially, it consists of a straight piece of metal with a hinge and a spring. Besides moving your vehicle's wiper across your windshield, a Mopar keeps the wiper firmly against the windshield. When it fails to do this, the arm's internal spring is likely to blame.
